Sony Launches New Burano CineAlta Camera

I was lucky enough to have been involved with a couple of the Sony Burano demo films as technical consultant and in addition I have now shot with it myself a few times.  You will find the main film I helped to shoot, shot with a pre-production Burano and mostly Cooke SP3 lenses  here: https://alphauniverse-mea.com/burano/.

So I though I would take a look at what it is and who it’s for. Everything written here is based on my experience with a pre-production camera, so there may be some small differences in the final release cameras.

Burano-sa1 Sony Launches New Burano CineAlta Camera

What is Burano?

 Sony’s Burano camera is a digital cinematography camera with an 8.6K sensor. It records to 3 different codecs, 16 bit X-OCN, and 10 bit XAVC-H and XAVC-I. It’s smaller than a Sony Venice and bigger than a Sony FX6. Overall, it is a similar size to the Sony FX9 and just a touch heavier. It has a PL lens mount and behind the PL mount there is a locking Sony E-Mount. It is expected to have a list price of 25,000 Euros.

The 8.6K sensor more than likely shares the same DNA as the sensor in the 8.6K Venice camera, but it is not the same sensor as Burano includes phase detection autofocus pixels and has a little more rolling shutter than Venice. Perhaps the Burano sensor is the same sensor as used in the Sony A1 camera. It’s no secret that the Venice 8.6K sensor and the Sony A1 sensor are very closely related. The autofocus in Burano is assisted by a dedicated AI processor.

burano-pl-mount2_1.4.1 Sony Launches New Burano CineAlta Camera

Burano has one of Sony’s very handy variable ND filters that smoothly goes from ¼ ND to 1/128th ND (2 to 6 stops). There is also a clear position where a clear optical flat replaces the ND.

Variable ND AND IBIS!

A first in Burano is the combination of both a variable ND filter and IBIS (In Body Stabilisation). The in body stabilisation is capable of working in conjunction with almost any lens attached to the camera including PL lenses.

CFExpress Type B.

Burano records to readily available CFExpress Type B cards, it is recommended that VPG400 cards are used but I have been able to use other fast cards not certified to the VPG400 standard (400MB/S sustained write speed). This represents a tremendous cost saving over the ultra expensive AXS cards required for Venice and while more expensive than SD cards, CFExpress cards are not crazy money. I successfully shot using 512GB Sabrent and Integral cards that cost around £150 ($200) each (the camera flashed up an unsupported media message, but I was able to record at all frame rates and resolutions including 4K 120fps and 8.6K 30fps X-OCN). The officially recommended cards are Sony’s VPG400 “tough” cards along with other brands of VPG400 cards, but these are more expensive.

Touchscreen LCD.

It is supplied with a good quality touchscreen LCD that can be used “as-is” or with a loupe attached to it. The optics in the loupe are pretty good and it uses a mirror to fold the optical path making it less long than the Loupe found on the FX9. BUT this mirror is in my opinion a very odd choice, more on that later. The LCD screen can be mounted to its mounting hardware in quite a few different ways allowing the camera to be adapted to many different shooting styles, again more details on this later.

burano-LCD_1.2.1 Sony Launches New Burano CineAlta Camera

V-Mount and 14 volts.

The camera has a V-Mount for V-Mount batteries as well as a 4 pin XLR input. No silly voltages here, it’s all industry standard 12v-16v. But one small omission is a complete lack of any DC out connectors on the camera body other than a USB-C port.

The bottom and top of the camera are completely flat, so it is very easy to add various base plates and I am sure there will be plenty of 3rd party cheese plate options etc. At IBC there were options from Vocas, Chrosziel and Tilta and I know there are accessories from Wooden Camera and Bright Tangerine in the pipelines.

Burano-SDI Sony Launches New Burano CineAlta Camera
Burano has an HDMI out and 2 SDI ouptuts, the top SDI is 12G, the lower SDI is 6G.

 

WHAT CAN IT RECORD?

8.6K Full Frame X-OCN-LT (and 8K XAVC-H +  4K & HD XAVC-I)

Burano has a few different scan sizes. The largest is an 8.6K scan of the full frame sensor at up to 30fps and this can be recorded to 16 X-OCN-LT or to the new H265 based XAVC-H codec. X-OCN is Sony’s raw codec, it takes everything the sensor captures, compresses it and records it in a very computer friendly 16 bit file.

Burano-ungraded1_1.17.1-scaled Sony Launches New Burano CineAlta Camera

This is the same codec as used by the Venice cameras. On a Venice there are 3 versions, XT (eXtended quality) ST (Standard Quality) and LT (Light). Even though LT is the smallest version of X-OCN the quality remains exceptionally good and I’ve used X-OCN-LT when shooting with the Venice cameras many times because my experience is that for most types of production the difference between LT and  XT is so small that LT is more than enough. Shooting at 8.6K and 30fps it is around 1.5Gb/s so you will get around 30 minutes on a 512GB card.

Burano-Monitoring Sony Launches New Burano CineAlta Camera

XAVC-H

XAVC-H is only for 8K recording. There are three versions of XAVC-H, all are 10 bit 4:2:2 and based on H265. XAVC-H-I-HQ is I frame only and goes up to 1200Mbps offering very high quality recordings. XAVC-H-I-SQ is the standard quality version going up to 800Mbps. Even at this bit rate the image quality remains very high, but if I wanted to shoot S-Log3 and grade, I would prefer XAVC-H-I-HQ. Shooting at XAVC-H-I-HQ you will get a little over an hour of 8K 30fps footage on a 512GB card when using the 8.6K scan mode.

Burano-Codecs1_1.12.1 Sony Launches New Burano CineAlta Camera

In addition there is a long GoP version, however the Long GoP version only supports 16:9. XAVC-H-L has a maximum bit rate of 520Mbps and actually the image quality is exceptionally good, comparable to the XAVC-H-I-HQ. But this codec need a lot of processing power in post production so may not be suitable for complex productions or anything where you have layers of clips.

Full Frame Scan – 6K recording.  Full Frame crop 6K

The next smaller scan size in what Sony rather confusingly calls Full Frame crop 6K. Unlike most other cameras the “6K” refers to the size of the recorded file, not the sensor scan. Sony haven’t publicly stated the number of pixels used, but according to my calculations it appears to be an 8K scan and the crop from Full Frame is very, very small. Only about 1.07x, less than 10%. The scan is then downsampled to 6K for recording.

For me this is a really nice option. The file sizes are half the size of the 8.6K scans, but because this is a downsample from the bayer sensor there is very little, if any, resolution loss (8K bayer resolves around 6K). I’m going to guess that this downsample to 6K is necessary to make recording X-OCN to CFExpress cards at 60 fps reliable. Recording X-OCN LT using the 6K scan mode at 30fps you will get around an hour of footage on a 512GB card. 

From the FF Crop 6K mode you can also record in 4K or HD using the XAVC-I codec.

Burano-scan-modes_1.5.1 Sony Launches New Burano CineAlta Camera
Selecting a new scan mode on Burano.


Going smaller, there is a Super35 mm 5.8K scan, recorded at either 5.8K with X-OCN or 4K or HD with XAVC-I. The image quality is not compromised in any way at any of the scan sizes, so there are no extra aliasing issues, no loss of dynamic range, no extra noise. So, this means that Burano is an excellent Super 35mm camera. At 5.8K using X-OCN LT at 30fps you will get a touch over 1 hour on a 512GB card.

In a future firmware update we are promised a 4:3 scan mode. 4:3 scan is the normally used aspect ration for classic super 35mm 2x anamorphic lenses. In addition we will get extra de-squeeze modes including 1.5x and 1.8x.

4K Scan and 120fps.

To shoot at more than 60fps we need to go down to a 4K scan. This is quite a small part of the sensor, the crop is around 2.15x from Full frame.  The good side is the image quality is no different to any of the other scan modes (other than resolution). The down side is you will need some pretty wide lenses for wide shots. But, for wild life shooters this will allow you to get closer to the action when shooting at up to 120fps.

Burano-Frame-Rates-1 Sony Launches New Burano CineAlta Camera
As you can see from the table above, XAVC-H is only available for the FF 8.6K scan mode. Once you drop down to the FF Crop 6K scan mode you can use XAVC-I to record in DCI 4K, UHD or HD.

Picture Quality.

It’s exceptionally good. And this is the thing, despite some of the cameras limitations and oddities (more on them later) Burano produces a beautiful image. The 16 bit X-OCN gives incredible post production flexibility and this is the codec you are going to want to use if you really want to get the best out of the camera. The subtleties the camera captures when shooting faces are sublime. The colour range is staggering and the linearity, the way colours don’t change or shift with brightness allows you to capture vast amounts of colour information from the deepest shadows to the brightest highlights.

SA-Shoot-red-string_2.1.2-scaled Sony Launches New Burano CineAlta Camera
Beautiful Skin tone textures from Sony Burano


The performance when shooting with XAVC-H is also very good, but you do loose some of the wonderful grading flexibility of the X-OCN.

When shooting at 8.6K with X-OCN-LT the images are almost indistinguishable from the images from a Venice 2, perhaps the only giveaway being more rolling shutter from Burano than Venice 2 (approx 16ms at 8.6k).

Burano’s sensor is a dual base ISO sensor, the base ISO’s are 800 and 3200 (the same as the 8.6K Venice 2). There is very little difference between the noise at each ISO and what noise there is very fine, almost film like. I actually like seeing the noise from Burano, it adds a subtle texture to the images that looks very nice.

SA-Shoot-Projector1_1.2.3-scaled Sony Launches New Burano CineAlta Camera
Shot at using Burano’s high base ISO of 3200.


Cameras like Sony’s FX6 already produce very good images, so, other than perhaps resolution, what is different about Burano’s images that makes me prefer it over the others? Frankly not a vast amount, we are already seeing the FX3 and FX6 being used on feature films, so we know they are very good. But what Burano has over the FX6 (like Venice) is an image that for me is more organic. It looks less electronic, less processed and there is a subtle richness to the colours not there in the FX3 or FX6. It is not a night and day difference, but it is a difference that makes me want to shoot with a Burano or Venice whenever I can. I suspect some of this comes from shooting at 8.6K or 5.8K and then down sampling to 4K, the extra resolution really helps with fine textures, colour resolution is greatly improved over a 4K sensor and the noise has a fineness to it that is very organic.

SA-Shoot-origami1_2.2.1-copy-scaled Sony Launches New Burano CineAlta Camera

 

Output Limitations:

One thing I discovered when using Burano to shoot X-OCN is that there are some output limitations. The camera has 2 SDI outputs, the top one is 12G and the lower one is 3G plus a 4K capable HDMI output. But when shooting using X-OCN these outputs are limited. You can’t have both SDI and HDMI at the same time and there is no way to get a 4K SDI output when shooting X-OCN. You can have 4K HDMI, but if you output 4K HDMI, you can’t have a LUT on the HDMI. In addition, if you are using the other codecs and want a LUT you can only get a LUT on the output when outputting HD. I was really surprised by these limitations.

 

Screenshot-2023-10-13-at-11.49.03 Sony Launches New Burano CineAlta Camera

 

This isn’t a cheap camera and the FX6 can output 4K and a LUT no matter how it’s setup. I had hoped that the FX9 was going to be the last camera with these sorts of restrictions, but alas no, Burano has them too. It’s very disappointing. But, I also acknowledge that not many people actually monitor on set at 4K (although 4K on a big monitor does make it much easier to see focus issues) and seeing as you have extremely high quality 16 bit internal recordings there isn’t really the need to output at 4K for an external recorder. 

Burano-sa7 Sony Launches New Burano CineAlta Camera

Better news is that even though there is no dedicated anamorphic scan mode the camera does support 2x and 1.3x monitoring De-Squeeze (with 1.5x and 1.8x to come in later firmware updates). But this is limited to when using the X-OCN codec. For anamorphic, until the 4:3 scan mode gets added via a later firmware update you should use the 8.6K FF scan modes wherever possible as this will be the correct height for super 35mm anamorphic lenses.

Even though you do need to do some cropping in post production, shooting 2x Anamorphic with a sensor that is nearly 5K tall and after cropping will be around 6K wide is absolutely fine for any type of delivery.

Cache Record, Interval Record and S&Q

Like most of Sony’s professional cameras Burano has cache record giving up to 30 seconds of pre-record cache and an interval record function. The cache can be combined with the S&Q mode (slow and quick) for slow motion and at 120fps is still a very decent 10 seconds (immediately I start thinking about shooting lightning and thunderstorms at 120fps using the cache).

And for those that don’t want to shoot X-OCN (raw) or S-Log3 Burano does have a full custom mode with S-Cinetone and Rec-709 gamma, pretty much the same as the FX6.

Ergonomics.

It’s a box, slightly smaller than the FX9. An almost square box, no weird curved base or odd shapes. Overall the camera body seems well laid out. The flat top and bottom makes mounting base plates and top plates easy. There is a V-Mount on the back, so no silly power adapters needed. On the right side of the camera there are 2 SDI connectors and HDMI connector plus connectors for genlock and timecode. You also have 2 full size XLR inputs. But there are a couple of omissions.

Burano-right-side Sony Launches New Burano CineAlta Camera
Right Side of the Sony Burano (not the 3rd party power breakout box between the battery and camera). Also the option arm and hand grip.

There is no DC power output other than a USB-C port. On a cinema camera you normally want a power output for accessories such as a follow focus or perhaps 3rd party monitor. But Burano has no power output. This means most will need to either use batteries with D-Taps or some sort of power module between the battery and camera. For the filming I’ve done with Burano I used a power breakout module between the battery and v-mount as this is a little bit safer than using D-Taps on a battery that you have to reconnect every time the battery has to be changed.

As an option you can buy an arm (Sony GPVR100) with a handgrip that is very similar to the arm used on the FX9. But the new arm includes a small lever that releases the arms pivot making it quick and easy to adjust the angle of the arm. This is a very big improvement over previous Sony arms. The new arm is also compatible with the FX6, but not the FX9. 

Top Handle and LCD Mounting.

burano-top-view Sony Launches New Burano CineAlta Camera

The camera is supplied with a very solid all metal top handle that bolts onto either the front or rear of the top of the camera. The handle then has a 15mm rod running through it for the viewfinder mounting system.

Burano-from-right Sony Launches New Burano CineAlta Camera

This IS an improvement over previous similar mounting systems as now the main support bar for the viewfinder is compatible with the Nato standard rather than Sony’s unique square rod or worse still the round rods that were in the FS7. But I do feel that the viewfinder mounting and ergonomics do let the camera down a bit, especially at the target price of 25K Euro/USD. There are certainly some odd design decisions.

Burano-Nato-rail Sony Launches New Burano CineAlta Camera
Burano Nato rail for the LCD


The LCD itself has two mounting points, one on it’s rear and one on the end. It attaches to a swivel joint and then the swivel attaches to the Nato rail. The swivel joint has a fixed level of tension, it’s pretty stiff, so won’t droop or sag, even with the eyepiece attached.

Burano-LCD-back Sony Launches New Burano CineAlta Camera

The combination of 2 different mounting points on the LCD screen and two different ways the swivel can be attached to the Nato rail allows you to mount the LCD on either side of the camera, either parallel with the camera body or sticking out at 90 degrees from the body.

Burano-LCD-swivel_1.6.1 Sony Launches New Burano CineAlta Camera

So far, so good.
By mounting the LCD on the right side of the camera it can be used by an assistant or AC much like the assistants control panel on a Venice. When you press the large “Home” button you get what Sony call the “Big 6” controls for frame rate, ISO, white balance, ND filter, shutter speed and monitoring.

Burano-Big-6_1.7.1 Sony Launches New Burano CineAlta Camera

When the Big 6 are being displayed the overlays on the SDI and HDMI are reduced to minimise clutter on an external monitor. Around the screen there are 6 buttons, one for each of the big 6 oryou can touch the screen to change the settings.

I expect most users of Burano will have the LCD screen mounted on the left side of the camera. If you attach the LCD parallel with the camera body you can then attach the high quality magnifier. This incorporates a mirror to keep the viewfinder assembly nice and compact. The housing is metal and the optics are high quality which is great. But why does it have a mirror?

Burano-using-loupe_1.8.1 Sony Launches New Burano CineAlta Camera
Shooting using the Sony Burano Loupe


You see – the LCD is a touch screen and I am sure there will be many times when you will want to use the magnifier/loupe as the screen is totally shaded from the sun so you see the correct contrast and you can see focus more easily. But with the LCD screen parallel with the camera body, when you flip the screen up, if the camera is on your shoulder, you can’t see the LCD making it impossible to use the touch functions or menus.

Burano-loupe-top_1.9.1 Sony Launches New Burano CineAlta Camera
When you open or remove the loupe the LCD can only be seen from the side of the camera

 

I know a lot of people don’t like the FX9 loupe because it’s long and plastic. But at least you could flip that up and see the screen. This one doesn’t make any sense. And what’s worse is that when you attach the viewfinder magnifier the buttons for the “Big 6” functions are inside the magnifier housing so can’t be used! Instead you’ll need to use the thumbstick which is on the far side of the LCD, hidden by the loupe assembly and tricky to get at. None of this makes any sense.

Burano-overlays_1.10.1 Sony Launches New Burano CineAlta Camera
The information overlays on Sony Burano are around the edge of the LCD image.


Which is such a shame, because on the LCD screen the information overlays are no longer over the image, they are around the edge of the screen and the screen itself is of reasonable quality. When used with the loupe it is a nice viewfinder and I am sure many will want to use it this way. I suspect we will see some 3rd party adapters to eliminate the mirror or allow the screen to flip out and then all these issues go away. One note is that the overlays are only around the edge of the image on the LCD screen. If outputting to an external monitor the overlays are over the main image (I believe there will be a later firmware update to allow the output of a monitoring image with the overlays around the outside of the image via the HDMI at some point).

Audio Inputs

Another oddity is that it isn’t easy to get more than 2 channels of audio into the camera. I have become used to having my external mics on channels 1 and 2 and then using the cameras internal mic on channel 3 and 4 as a backup. But with only 2 analog XLRs you only have 2 inputs! The camera does have a small scratch mic on the operators side, but there is no other microphone built in to the camera. There is a way to get more than 2 channels of audio in and it and it involves the use of the top handle from the FX9. On the top of the Burano camera there is a little cover and under the cover there is the same connector as there is on the top of the FX9. And, Burano can take the FX9 top handle instead of the suppled handle. This then gives you the ability to use the MI Shoe on the FX9’s handle to feed 2 more channels of audio into the camera. The FX9 handle can be purchased from a Sony dealer as a spare part. But I have to say, when you are spending 25K Euro/USD  on a camera this is a bit disappointing. Please Sony, make a small breakout box.

Variable ND and IBIS.

Burano has Sony’s Full Frame variable ND filter system. This is so easy to use and a great feature. There is a clear position and then when the ND filter comes in the minimum ND is 2 stops going all the way to 8 stops. There is a rotary dial on the left side of the camera for variable ND, or you can set the ND filter to work in 1 stop steps which can then be controlled via the Big 6 home menu or the plus and minus buttons. The variable ND can also be controlled automatically by the cameras auto exposure system which is an interesting option particularly when shooting with PL lenses. In addition when using a Sony E-Mount lens and the variable ND is engaged you can use the “Bokeh Control” function that ties the ND filter and the lenses iris together to maintain a constant image brightness. By turning the iris control you can alter the depth of field and Bokeh while the brightness stays the same.

Burano-ND-wheel_1.11.1 Sony Launches New Burano CineAlta Camera

IBIS 
One of the big surprises though is the addition of IBIS in body stabilisation because for a long time Sony said that having both together wasn’t possible. IBIS works with any lens, including unstabilised PL lenses. What’s more it’s really good. There are a couple of different levels of stabilisation including an off setting. When shooting in Full Frame you are limited to the Low setting – which works very well at removing low levels of camera shake, its great for steadying up a handheld shot. When using a PL (or other non Sony E-Mount lens) you must set the focal length of the lens manually to get the best results. Set too long a focal length setting and the image will be over stabilised, making it more jittery and wobbly. Set a shorter focal length than that of the lens and you get less stabilisation, this might be handy if you want only a very small amount of stabilisation.

Burano-PL-stabilisation_1.13.1 Sony Launches New Burano CineAlta Camera
Sony Burano PL Stabilisation

 

When shooting using the s35 5.8K scan mode and XAVC-I there is a high setting for PL and other non Sony lenses as well as an active setting for Sony E-mount lenses. This does introduce a small additional crop into the image but is very good at taking out a lot of camera shake. These modes only work when recording XAVC-H or XAVC-I, the high and active modes don’t work with X-OCN. However active mode does tend to “grab” a little bit, taking out a lot of shake and wobble until it can’t take any more out and then suddenly the image jerks a bit and then grabs a new stable position. I myself am not a big fan of the active mode, but its handy to have it in reserve for those times you are really struggling to get a stable shot, perhaps from a helicopter or boat.

One small issue with adding IBIS to a digital cinema camera is that because the sensor can move there could be small image shifts when the camera is used locked off, shut down and then restarted. 

AS well as IBIS Burano has gyro sensors and the gyro data is recorded as metadata to allow footage to be stabilised in post production. To use the Gyro data IBIS should be turned off or you should use the PL Hi or E-Mount Active modes.

One note here – when you remove or refit the PL mount you MUST turn the camera off. When you turn the camera on it checks to see whether the PL Mount is fitted or not and then makes adaptations to the menu options based on whether the camera thinks you have the PL mount attached or not.

Autofocus with AI processing.

Burano-af-tracking_2.1.1 Sony Launches New Burano CineAlta Camera
Sony Burano autofocus with AI and human tracking.

 

Burano has autofocus. It has Sony’s excellent fast hybrid autofocus system and we all know how good that is. It even has a new AI based processing chip to assist with the object tracking and human detection. The autofocus can be driven using the LCD touch screen, simply touch where you want the camera to focus and it will then track that object. It can be set to recognise “Humans” and will prioritise Humans over anything else in the shot, focussing on the profile of a human, even if they are not facing the camera and then when they turn towards the camear it will focus on the persons face or eyes. It works exceptionally well. It is also highly programmable with the usual settings for responsiveness and focus speed that we see in cameras like the FX6 and FX3.

I think it will be quite interesting to see whether high end film makers will, or will not, use autofocus. Burano gives Venice image quality but with the ability to use AF if you want. It might end up used on very big features for action scenes or other shots where focus is particularly challenging. It will be great for use on gimbals and stabilisers. The projects I have been involved have used gimbals and drones. Burano balances really easily, much more easily than a Venice on most drones and gimbals. And for drone work it is so much lighter than a Venice or most other 8K digital cinema cameras. I’ve even managed to get it balanced on a DJI RS3 (using the Cooke SP3 lenses).

So, who is it for?

Burano seems to me to be the Sony F55 replacement that so many have been looking for since the F55 was discontinued. But it’s more than that. We have seen that it is possible to shoot a big budget feature film with the Sony FX3, so there really is no reason why you can’t use Burano on very high end features. Burano isn’t that much heavier than a Sony Rialto, so I can see some productions that might have had a Rialto on set swapping the Rialto for a Burano – with Burano there is no umbilical cable to worry about.

Burano-Ronin2 Sony Launches New Burano CineAlta Camera

It will be a great camera for documentary production where you want Venice image quality but without the expense or weight. Although it is worth noting that it is bigger and heavier than an FX6 (but very slightly smaller than the FX9), so it won’t suit every production.
Wildlife productions will likely be very happy to get a camera that can deliver both 8K resolution for re-framing as well as offering different crop modes for when tighter shots are needed. The ability to switch near instantly between the different crop modes will be highly beneficial as will the speed at which the camera turns on.

Burano-assign-crop_1.12.2 Sony Launches New Burano CineAlta Camera
Assigning Crop Select to an assignable button makes switching between the different crop modes very fast on Sony Burano



A key Burano strength is its ability to shoot over sampled super 35. I think we will see a resurgence in the use of Super 35 especially for productions that need zoom lenses. There are far more lens options for Super 35 than full frame. Super 35mm lenses have been around for a very long time so there is a wealth of lenses to choose from. So, for anyone that needs a really good s35 camera Burano will be a great option. And compared to other cameras that shoot at s35, as well as the oversampling there is the dual ISO performance,  Burano is great in low light. The base ISO’s are the same as Venice 2, 800 ISO at low base and 3200 ISO at high base. Even at high base the noise is minimal and quite pretty looking.

Burano will be a lower cost, high quality option for anyone that needs to deliver in 8K (as long as you don’t need to go above 30fps). Although I don’t think there are many actually doing this right now and it will be some time before 8K delivery becomes common (if it ever does). I’ve had to deliver a couple of 8K productions but they are the exception, most of what I deliver is 4K and its likely to stay that way for some time yet.

I think Burano will have a very broad appeal. It is perhaps a bit on the expensive side for a lot of those that currently use the FX6 or FX9, and let’s face it, the FX6/FX9 does produce really nice pictures. I think it only has limited appeal for TV News, but for those shooting docs it will be a really nice choice.

But what about some of the negatives I have pointed out?

Well, I really wish they weren’t there and they are frustrating. But none of them are show stoppers. I really want the flexibility to shoot from 8K full frame to super 35, to record with 16 bit X-OCN at up to 120fps. I want the colour response and dynamic range. I love the idea of IBIS with PL lenses and autofocus with Sony lenses. I can live with only a HD SDI output when shooting full frame  X-OCN, after all I don’t need to record externally when the internal X-OCN is so good. I’ll figure out how to get around the strange LCD/Loupe situation, I’m sure there will be some 3rd party solutions.
I can perhaps live with only 2 channels of audio (unless I add the FX9 top handle). So, overall I am really am excited about doing more with Burano. It fills the gap that was left when the F5 and F55 were discontinued and will be a great option for a lot of productions looking to bridge that gap between the FX9 and Venice. For many people, myself included Venice is out of my price range, Venice is a camera I rent when I need it. Burano offers most of the same image quality but at a much more affordable price, especially when media costs are factored in (the AXS cards for needed for the 8K Venice are around £4K each). Burano’s FF Crop 6K scan modes are going to be perfect for documentary productions allowing you to benefit from the near full frame 8K scan to 6K recording, it’s oversampled  while halving the file size compared to recording at 8K.

When can you get one? Originally it was going to be available very early 2024, but in the last few days this has been put back to Spring 2024 – It’s going to be a long wait, but I think well worth the wait.

Removing Screws From Sony Cameras

Although I wouldn’t normally recommend removing the screws from Sony cameras there are times when this is something you need to do, for example to remove the microphone mount on an FX6.

Most of the small screws have a thread locking compound applied to the threads to prevent them from shaking or vibrating loose. This can make them hard to unscrew. 

JIS NOT Phillips!!

The main issue is that most cross of the commonly found small and miniature head screw drivers are manufactured to the “Philips” standard. But the screws used on the Sony cameras are manufactured to the JIS standard. The differences between these two very similar looking standards means that you will not get a secure and tight fit between a Philips screw driver and a JIS screw head. The edges of a Philips screwdriver are at an angle that is too shallow to properly engage with the full depth of a JIS screw head. So when you try to undo a tight screw the head of the screw will deform or strip, often  to the point where it can’t be undone.

Whenever working on Sony cameras you should use JIS standard screwdrivers and ensure the screwdriver is the correct size for the screws you are working with. The smaller screws used for thing like the microphone mount on the FX and Alpha series cameras are JIS size +0 or +00. A JIS size +0 seems to fit most but I would also get a +00.

Don’t try to use a miniature Philips screwdriver on a tight JIS screw. It might look like it fits, but only a very small part of the screwdriver head will be correctly engaged with the JIS screw and once the screw head is damaged you can’t undo the damage and it may become impossible to remove the screw without drilling it out. 

If you search for “Vessel JIS” you should be able to find good quality small and miniature JIS  screwdrivers on Amazon, ebay or from other suppliers.

Sony Launches Venice II

Screenshot-2021-11-12-at-10.02.54-e1636988898904-600x436 Sony Launches Venice II
Sony Venice II

 

Today Sony launched Venice II. Perhaps not one of the very best kept secrets with many leaks in the last few weeks, but finally we officially know that it’s called Venice II and it has an 8K (8.6K maximum) sensor recording 16 bit linear X-OCN or ProRes to 2 built in AXS card slots.

The full information about the new camera is here. https://pro.sony/en_GB/products/digital-cinema-cameras/venice2

Venice II is in essence the original Venice camera and the AXS-R7 all built into a single unit.  But to achieve this the ability to use SxS cards has been dropped, Venice II only works with AXS cards. The XAVC-I codec is also gone. The new camera is only marginally longer than the original Venice camera body.

As well as X-OCN (the equivalent of a compressed raw recording) Venice II can also record 4K ProRes HQ and 4K ProRes 444. Because the sensor is an 8.6K sensor that 4K 444 will be “real” 444 with a real Red, Green and Blue sample at every position in the image. This will be a great format for those not wishing to use X-OCN. But why not use X-OCN? the files are very compact and full of 16 bit goodness. I find X-OCN just as easy to work with as ProRes.

One thing that Venice II can’t do is record proxies. Apparently user feedback is that these are rarely used. I guess in a film style workflow where you have an on set DIT station it’s easy for proxies to be created on set. Or you can create proxies in most edit applications when you ingest the main files, but I do wonder if proxies are something some people will miss if they only have X-OCN files to work from.

New Sensor:

There has been a lot of speculation that the sensor used in Venice II is the same as the sensor in the Sony A1 mirrorless camera, after all the pixel count is exactly the same. We already know that the A1 sensor is a very nice and very capable sensor. So IF it were to be the same sensor but paired with significantly more and better processing power and an appropriate feature set for digital cinema production it would not be anything to complain about. But it is unlikely that it is the very same sensor. It might be based on the A1 sensor (and the original Venice sensor is widely speculated to be based on the A9 sensor) but one thing you don’t want on these sensors are the phase detection sites used for autofocus.

When you expand these very high quality images on to very big screens, even the smallest of image imperfections can become an issue. The phase detection pixels and the wires that interconnect them can form a very, very faint fixed pattern within the image. In a still photograph you would probably never see this. In a highly compressed image, compression artefacts might hide it (although both the FX6 and FX9 exhibit some fixed pattern noise that might in part be caused by the AF sites). But on a giant screen, with a moving image this faint fixed pattern may be perceptible to audiences and that just isn’t acceptable for a flagship cinema camera. So, I am led to believe that the sensors used in both the original Venice and Venice II do not have any AF phase detection pixels or wire interconnects. Which means these can not the very same sensors as found in the A1 or A9. They are most likely specifically made for Venice.
Also most stills camera based sensors are only able to be read at 12 bit when used for video, again perhaps a key difference is that when used with the cooling system in the Venice cameras these sensors can be read at 16 bit at video frame rates rather than 12 or 14 bits.

The processing hardware in Venice II has been significantly upgraded from the original Venice. This was necessary to support the data throughput need to shoot at 8.6K and 60fps as well as the higher resolution SDI outputs and much improved LUT processing.  Venice II can also be painted live on set via both wiFi and Ethernet. So the very similar exterior appearances do in fact hide the fact that this really is a completely new camera.

Screenshot-2021-11-12-at-10.09.29-e1636989513212-600x318 Sony Launches Venice II

My Highlights:

I am not going to repeat all the information in the press releases or on the Sony website here. But what I will say is I like what I see. Integrating the R7 into the Venice II body makes the overall package smaller. There are no interconnections to go wrong. The increase in dynamic range to 16 stops, largely thanks to a lower noise floor is very welcome. There was nothing wrong with the original Venice, but this new sensor is just that bit better.

The default dynamic range split gives the same +6 stops as most of Sony’s current cameras but goes down to -10 stops.  But with the very low noise floor that this sensor has rating the camera higher than the rated  800 base ISO to gain a bit of extra headroom shouldn’t be an issue. Sample footage from Venice II shows that the way the highlights do reach their limits is very nice.

The LUT processing has been improved and now you can have 3D LUTs in 4K on SDI’s 1&2 which are 12G and in HD at the same time on SDI’s 3&4 which are 3G – as well as on the monitor out and in the VF. This is actually quite a significant upgrade, the original Vence is a little bit lacking in  the way it handles LUTs. The ART look system is retained if you want even higher quality previews than that possible with 33x LUTs. There is also built in ACES support with a new RRT, this makes the camera extremely easy to use for ACES workflows and the 16 bit linear X-OCN is a great fit for ACES.

It retains the ability to remove the sensor head so it can be used on the end of an extension cable. Venice II can use either the original 6K Venice sensor or the new 8K sensor, however a new extension cable which won’t be available until until some time in 2023 is needed before the head can be separated, so Venice 1 will still have a place for some considerable time to come.

Screenshot-2021-11-12-at-10.05.00-e1636989382866-600x292 Sony Launches Venice II
Venice only takes the original 6K sensor but Venice II can take either the original 6K sensor or the new 8K sensor.



Moving the dual ISO from 500/2500 to 800/3200 brings Venice II’s lower base ISO up to the same level as the majority of other Cinema cameras. I know that some found 500 ISO slightly odd to work with. This will just make it easier to work alongside other similarly rated cameras.

Another interesting consideration is that you can shoot at 5.8K pixels with a Super 35mm sized scan. This means that the 4K Super 35mm material will have greater resolution than the original Venice or many other S35 cameras that only use 4K of pixels at S35. There is a lot of very beautiful super 35mm cine glass available and being able to shoot using classic cinema glass and get a nice uplift in the image resolution is going to be really nice. Additionally there will be some productions where the shallower DoF of Full Frame may not be desirable or where the 8.6K files are too big and unnecessary. I can see Venice II being a very nice option for those wishing to shoot Super 35.

But where does this leave existing Venice owners? 

For a start the price of Venice 1 is not going to change. Sony are not dropping the cost. This new Venice is an upgrade over the original and more expensive (but the price does include the high frame rate options). Although my suspicion is that Venice II will not be significantly more expensive that the cost of the current Venice + R7 + HFR licence. Sony want this camera to sell well, so they won’t want to make it significantly more as then many would just stick with Venice 1. The original remains a highly capable camera that produces beautiful images and if you don’t need 8.6K the reasons to upgrade are fewer. The basic colour science of both cameras remains the same, so there is no reason why both can’t be used together on the same projects. Venice 1 can work with lower cost SxS cards and XAVC-I if you need very small files and a very simple workflow, Venice II pushes you to a AXS card based workflow and AXS cards are very expensive. 

If you have productions that need the Rialto system and the ability to un-dock the sensor, then this isn’t going to be available for Venice II for some time. So original Venice cameras will still be needed for Rialto applications (it will be 2023 before Rialto for Venice II becomes available).

Of course it always hurts when a new camera comes out, but I don’t think existing Venice owners should be too concerned.  If customers really felt they needed 8.6K then they would have already likely been lost to a Red camera and the Red ecosystem. But at least now that there is an 8K Venice option that might help keep the original Venice viable for second unit, Rialto (for now at least) or secondary roles within productions shooting primarily in 8K.

I like everything I see about Venice II, but it doesn’t make Venice 1 any less of a camera.


Beware Fake Sony BP-U Batteries!

Fake-real-bpu-600x225 Beware Fake Sony BP-U Batteries!Can you tell which is genuine and which is fake? It would appear that a number of fake BP-U batteries are starting to show up on ebay and other less reputable places. The battery on the left won’t charge on a genuine Sony charger, this tells me it is not a real Sony battery.

If you look at the labels on the batteries the quality of the printing on the fake battery on the left is not as fine as on the genuine battery, in particular the ® as well as the box around the level indicator LED’s is not as crisply and finely printed.

The sellers are clever. These are not so cheap as to raise suspicion, they just seem very competitively priced. These batteries might be a little bit cheaper, but how safe are they and how long will they last? I have to say this would have fooled me and I have a lot of sympathy for others that have been tricked into buying these. But if the manufacturer can’t sell these by legitimate means under their own brand name I really do have to question their quality and safety.

3rd Party BP-U style batteries And Sony Camcorders (Update)

I wish to update and present the facts that I have regarding potential issues with mainly older 3rd party PB-U batteries. This isn’t here as a scare story, I’m not trying to sensationalise this, just present the facts that I have to hopefully clarify the current situation.

In 2019 I became aware that it was suddenly becoming very hard to buy 3rd party BP-U batteries. Dealers didn’t have any and you couldn’t find them anywhere. Talking to a couple of manufacturers I was informed that they had been told to stop making BP-U batteries.

Then I learnt from Sony that they had been getting an unusually large number of their more recent cameras in for repair, cameras that had suddenly and inexplicably stopped working. They traced this to design issues in some 3rd party batteries that resulted in power flowing through the batteries data pins, damaging beyond repair the cameras motherboard. It was not a case of a battery being inserted incorrectly, it was an issue with the circuitry in the battery.

As a result of this Sony took action in 2019 to prevent the manufacture of 3rd party BP-U batteries and that’s why you could no longer get them.

Since then however it would appear that the manufacture of 3rd party batteries is once again in full swing. In addition I’ve noticed that some older models have been discontinued, often with new versions replacing them, perhaps a “B” version or a model number numerically higher than before.

From this I must assume that whatever the issue was, it has now been resolved and that the 3rd party BP-U batteries on sale today should be perfectly safe to use with our cameras. I would have no hesitation in today buying a brand new BP-U battery from any of the reputable brands.

I have nothing to gain here. This is not a campaign to make you all buy Sony batteries. Even though Sony do make a very fine battery, I too use 3rd party batteries as I need the D-Tap port found only on 3rd party batteries.

But clearly there was a very real battery issue. I’m led to understand that the cost to repair these damaged cameras was over $1K. While not every user of these batteries ends up with a dead camera, I think you have to ask yourself – is it worth using batteries made in 2019 or earlier? I won’t list the batteries that I know to have problems because the list may be incomplete. Just because a battery is not on the list it would not be a guarantee that it’s safe. However if any 3rd party battery manufacturer is reading this and has the confidence to provide me with a list of batteries that they will guarantee are safe, I will gladly publish that (January 2022 and not one manufacture has provided any information).

Clearly not everyone ends up with a dead camera, perhaps the majority have no issue, but enough did that Sony had to take action and it appears that the manufacturers responded by checking and adjusting their designs if necessary.

So my advice is: Don’t use 3rd party batteries made prior to 2020.  

If you do, then make absolutely sure the camera is completely powered down when inserting or removing the battery. 

I believe that any BP-U battery made in 2020 or later should be safe to use. So please think about replacing any old batteries with new ones, or perhaps contact your battery supplier and ask if what you have is safe. However you should be aware that since 2019 Sony’s own BP-U battery chargers will no longer charge 3rd party batteries.

The information I have presented here is correct to the best of my knowledge and I hope you will use it to make your own decision about which batteries to use.

Do the images from my Sony camera have to look the way they do?

— And why do Sony cameras look the way they do?

It all about the color science.

“Color Science” is one of those currently in fashion phrases that gets thrown around all over the place today. First of all – what the heck is color science anyway? Simply put it’s how the camera sees the colors in a scene, mixes them together, records them – and then how your editing or grading software interprets what is in the recording and finally how the TV or other display device turns the digital values it receives back into a color image. It’s a combination of optical filters such as the low pass filter, color filters, sensor properties, how the sensor is read out and how the signals are electronically processed both in the camera, by your edit/grading system and by the display device. It is no one single thing, and it’s important to understand that your edit process also contributes to the overall color science.

Color Science is something we have been doing since the very first color cameras, it’s not anything new. However us end users now have a much greater ability to modify that color science thanks to better post production tools and in camera adjustments such as picture profiles or scene files.

Recently, Sony cameras have sometimes been seen by some as having less advanced or poor color science compared to cameras from some other manufacturers. Is this really the case? For Sony part of the color science issue is that historically Sony have deliberately designed their newest cameras to match previous generations of cameras so that a large organisation with multiple cameras can use new cameras without having them look radically different to their old ones. It has always been like this and all the manufacturers do this, Panasonic cameras have a certain look as do Canon etc. New and old Panasonics tend to look the same as do old and new Canon’s, but the Canon’s look different to the Panasonics which look different to the Sony’s.

Sony have a very long heritage in broadcast TV and that’s how their cameras look out of the box, like Rec-709 TV cameras with colors that are similar to the tube cameras they were producing 20 years ago. Sony’s broadcast color science is really very accurate – point one at a test chart such as a Chroma DuMonde and you’ll see highly repeatable, consistent and accurate color reproduction with all the vectors on a vector scope falling exactly where they should, including the skin tone line.

On the one hand this is great if you are that big multi-camera business wanting to add new cameras to old ones without problems, where you want your latest ENG or self-shooters cameras to have the same colors as your perhaps older studio cameras so that any video inserts into a studio show cut in and out smoothly with a consistent look.

But on the other hand it’s not so good if you are a one man band shooter that wants something that looks different. Plus accurate is not always “pretty” and you can’t get away from the fact that the pictures look like Rec-709 television pictures in a new world of digital cinematography where TV is perhaps seen as bad and the holy grail is now a very different kind of look that is more stylised and much less true to life.

So Sony have been a bit stuck. The standard look you get when you apply any of the standard off-the shelf S-Log3 or S-Log2 LUT’s will by design be based on the Sony color science of old, so you get the Sony look. Most edit and grading applications are using transforms for S-Log2/3 based on Sony’s old standard Rec-709 look to maintain this consistency of look. This isn’t a mistake. It’s by design, it’s a Sony camera so it’s supposed to look like other Sony cameras, not different.

But for many this isn’t what they want. They want a camera that looks different, perhaps the “film look” – whatever that is?

Recently we have seen two new cameras from Sony that out of the box look very different from all the others. Sony’s high end Venice camera and the lower cost FS5 MKII. The FS5 MKII in particular proves that it’s possible to have a very different look with Sony’s existing colour filters and sensors. The FS5 MK II has exactly the same sensor with exactly the same electronics as the MK I. The only difference is in the way the RGB data from the sensor is being processed and mixed together (determined by the different firmware in the Mk1 and mk2) to create the final output.

The sensors Sony manufacture and use are very good at capturing color. Sony sensors are found in cameras from many different manufacturers. The recording systems in the Sony cameras do a fine job of recording those colors as data within the files the camera records as data with different code values representing what the sensor saw. Take that data into almost any half decent grading software and you can change the way it looks by modifying the data values. In post production I can turn almost any color I want into any other color. It’s really up to us as to how we translate the code values in the files into the colors we see on the screen, especially when recording using Log or raw. A 3D LUT can change tones and hues very easily by shifting and modifying the code values. So really there is no reason why you have to have the Sony 709 look.

My Venice emulation LUT’s will make S-Log3 from an FS5 or FS7 look quite different to the old Sony Broadcast look. I also have LUT’s for Sony cameras that emulate different Fuji and Kodak film stocks, apply one of these and it really looks nothing like a Sony broadcast camera. Another alternative is to use a color managed workflow such as ACES which will attempt to make just about every camera on the market look the same applying the ACES film style look and highlight roll-off.

We have seen it time and time again where Sony footage has been graded well and it then becomes all but impossible to identify what camera shot it. If you have Netflix take a look at “The Crown” shot on Sony’s F55 (which has the same default Sony look as the FS5 MK1, FS7 etc). Most people find it hard to believe the Crown was shot with a Sony because it has not even the slightest hint of the old Sony broadcast look.

If you use default settings, standard LUT’s etc it will look like a Sony, it’s supposed to! But you have the freedom to choose from a vast range of alternative looks or better still create your own looks and styles with your own grading choices.

But for many this can prove tricky as often they will start with a standard Sony LUT or standard Sony transform. So the image they start with has the old Sony look. When you start to grade or adjust this it can sometimes look wrong because you have perhaps become used to the original Sony image and then anything else just doesn’t seem right, because it’s not what you are used to. In addition if you add a LUT and then grade, elements of the LUT’s look may be hard to remove, things like the highlight roll off will be hard baked into the material, so you need to do need to think carefully about how you use LUT’s. So try to break away from standard LUT’s. Try ACES or try some other starting point for your grade.

Going forward I think it is likely that we will see the new Venice look become standard across all of the Cinema style cameras from Sony, but it will take time for this to trickle down into all the grading and editing software that currently uses transforms for s-Log2/3 that are based on the old Sony Rec-709 broadcast look. But if you grade your footage for yourself you can create just about any look you want.

Sony Venice. Dual ISO’s, 1 stop ND’s and Grading via Metadata.

With the first of the production Venice cameras now starting to find their way to some very lucky owners it’s time to take a look at some features that are not always well understood, or that perhaps no one has told you about yet.

Dual Native ISO’s: What does this mean?

An electronic camera uses a piece of silicon to convert photons of light into electrons of electricity. The efficiency at doing this is determined by the material used. Then the amount of light that can be captured and thus the sensitivity is determined by the size of the pixels. So, unless you physically change the sensor for one with different sized pixels (which will in the future be possible with Venice) you can’t change the true sensitivity of the camera. All you can do is adjust the electronic parameters.

With most video cameras the ISO is changed by increasing the amount of amplification applied to the signal coming off the sensor. Adding more gain or increasing the amplification will result in a brighter picture. But if you add more amplification/gain then the noise from the sensor is also amplified by the same amount. Make the picture twice as bright and normally the noise doubles.

In addition there is normally an optimum amount of gain where the full range of the signal coming from the sensor will be matched perfectly with the full recording range of the chosen gamma curve. This optimum gain level is what we normally call the “Native ISO”. If you add too much gain the brightest signal from the sensor would be amplified too much and exceed the recording range of the gamma curve. Apply too little gain and your recordings will never reach the optimum level and darker parts of the image may be too dark to be seen.

As a result the Native ISO is where you have the best match of sensor output to gain. Not too much, not too little and hopefully low noise. This is typically also referred to as 0dB gain in an electronic camera and normally there is only 1 gain level where this perfect harmony between sensor, gain and recording range is achieved, this becoming the native ISO.

Side Note: On an electronic camera ISO is an exposure rating, not a sensitivity measurement. Enter the cameras ISO rating into a light meter and you will get the correct exposure. But it doesn’t really tell you how sensitive the camera is as ISO has no allowance for increasing noise levels which will limit the darkest thing a camera can see.

Tweaking the sensor.

However, there are some things we can tweak on the sensor that effect how big the signal coming from the sensor is. The sensors pixels are analog devices. A photon of electricity hits the silicone photo receptor (pixel) and it gets converted into an electron of electricity which is then stored within the structure of the pixel as an analog signal until the pixel is read out by a circuit that converts the analog signal to a digital one, at the same time adding a degree of noise reduction. It’s possible to shift the range that the A to D converter operates over and the amount of noise reduction applied to obtain a different readout range from the sensor. By doing this (and/or other similar techniques, Venice may use some other method) it’s possible to produce a single sensor with more than one native ISO.

A camera with dual ISO’s will have two different operating ranges. One tuned for higher light levels and one tuned for lower light levels. Venice will have two exposure ratings: 500 ISO for brighter scenes and 2500 ISO for shooting when you have less light. With a conventional camera, to go from 500 ISO to 2500 ISO you would need to add just over 12dB of gain and this would increase the noise by a factor of more than 4. However with Venice and it’s dual ISO’s, as we are not adding gain but instead altering the way the sensor is operating the noise difference between 500 ISO and 2500 ISO will be very small.

You will have the same dynamic range at both ISO’s. But you can choose whether to shoot at 500 ISO for super clean images at a sensitivity not that dissimilar to traditional film stocks. This low ISO makes it easy to run lenses at wide apertures for the greatest control over the depth of field. Or you can choose to shoot at the equivalent of 2500 ISO without incurring a big noise penalty.

One of Venice’s key features is that it’s designed to work with Anamorphic lenses. Often Anamorphic lenses are typically not as fast as their spherical counterparts. Furthermore some Anamorphic lenses (particularly vintage lenses) need to be stopped down a little to prevent excessive softness at the edges. So having a second higher ISO rating will make it easier to work with slower lenses or in lower light ranges.

COMBINING DUAL ISO WITH 1 STOP ND’s.

Next it’s worth thinking about how you might want to use the cameras ND filters. Film cameras don’t have built in ND filters. An Arri Alexa does not have built in ND’s. So most cinematographers will work on the basis of a cinema camera having a single recording sensitivity.

The ND filters in Venice provide uniform, full spectrum light attenuation. Sony are incredibly fussy over the materials they use for their ND filters and you can be sure that the filters in Venice do not degrade the image. I was present for the pre-shoot tests for the European demo film and a lot of time was spent testing them. We couldn’t find any issues. If you introduce 1 stop of ND, the camera becomes 1 stop less sensitive to light.  In practice this is no different to having a camera with a sensor 1 stop less sensitive. So the built in ND filters, can if you choose, be used to modify the base sensitivity of the camera in 1 stop increments, up to 8 stops lower.

So with the dual ISO’s and the ND’s combined you have a camera that you can setup to operate at the equivalent of 2 ISO all the way up to 2500 ISO in 1 stop steps (by using 2500 ISO and 500 together you can have approximately half stops steps between 10 ISO and 650 ISO). That’s an impressive range and at no stage are you adding extra gain. There is no other camera on the market that can do this.

On top of all this we do of course still have the ability to alter the Exposure Index of the cameras LUT’s to offset the exposure to move the exposure mid point up and down within the dynamic range. Talking of LUT’s I hope to have some very interesting news about the LUT’s for Venice. I’ve seen a glimpse of the future and I have to say it looks really good!

METADATA GRADING.

The raw and X-OCN material from a Venice camera (and from a PMW-F55 or F5 with the R7 recorder) contains a lot of dynamic metadata. This metadata tells the decoder in your grading software exactly how to handle the linear sensor data stored in the files. It tells your software where in the recorded data range the shadows start and finish, where the mid range sits and where the highlights start and finish. It also informs the software how to decode the colors you have recorded.

I recently spent some time with Sony Europe’s color grading guru Pablo Garcia at the Digital Motion Picture Center in Pinewood. He showed me how you can manipulate this metadata to alter the way the X-OCN is decoded to change the look of the images you bring into the grading suite. Using a beta version of Black Magic’s DaVinci Resolve software, Pablo was able to go into the clips metadata in real time and simply by scrubbing over the metadata settings adjust the shadows, mids and highlights BEFORE the X-OCN was decoded. It was really incredible to see the amount of data that Venice captures in the highlights and shadows. By adjusting the metadata you are tailoring the the way the file is being decoded to suit your own needs and getting the very best video information for the grade. Need more highlight data – you got it. Want to boost the shadows, you can, at the file data level before it’s converted to a traditional video signal.

It’s impressive stuff as you are manipulating the way the 16 bit linear sensor data is decoded rather than a traditional workflow which is to decode the footage to a generic intermediate file and then adjust that. This is just one of the many features that X-OCN from the Sony Venice offers. It’s even more incredible when you consider that a 16 bit linear  X-OCN LT file is similar in size to 10 bit XAVC-I(class 480) and around half the size of Apples 10 bit ProRes HQ.  X-OCN LT looks fantastic and in my opinion grades better than XAVC S-Log. Of course for a high end production you will probably use the regular X-OCN ST codec rather than the LT version, but ST is still smaller than ProRes HQ. What’s more X-OCN is not particularly processor intensive, it’s certainly much easier to work with X-OCN than cDNG. It’s a truly remarkable technology from Sony.

Next week I will be shooting some more test with a Venice camera as we explore the limits of what it can do. I’ll try and get some files for you to play with.
